MULTIPLE FENCE-SHEAR.

Specification of Letters Patent.

Patented Sept. 17, 1907,

Application filed \Tune 18, 1906. Serial No. 322,191-

To all whom it'may concern:

Be it known that I, ROBERT W. NEY, of Cleveland, Cuyahoga county, Ohio,have invented a new and useful Multiple Fence-Shear, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure 1 is a front elevation of my improved shear device; Fig. 2is a side elevation of the same; Fig. 3 is a cross section on the lineIIIIII of Fig. 2; and Figs. 4 and 5 are respectively a plan and a sideelevation showing the preferred arrangement of my improved shear in afence machine.

My invention relates to shearing the wires of fence or wire fabric, andis designed to provide a simple and improved device for simultaneouslycutting a series of these wires.

The invention is specially designed as an attachment to a wire fencemachine; and in such case is employed to cut the longitudinal wiresafter the required length of fence has been wound on a take-up spool. Itmay, however, be used in other locations and with any desired type offence or wire fabric having a series of wires extending in the samedirection and which are to be severed.

In the drawings, in which I show a preferred form of the invention, 2represents the stationary vertical' shear blade, which is bolted at itslower end to a V- shaped shoe or slide 3 adjustable horizontally in thestationary base-plate 4 of the fence-making machine. This base-plate isprovided with adjustable and removable guides 5 lapping over theV-flanges oi the shoe or slide.

The top of the stationary shear-blade is preferably secured and bracedby the slotted guide-bar 6, fastened to the upper part of the machineframe and through a slot in which the stationary blade extends.

The movable shear blade 7 is preferably of less width than thestationary shear blade, and is connected therewith by a series of bolts8 which extend through holes in the stationary blade and through widenedslots or holes in the movable blade.

The knives or cutter blades 9 preferably are formed of hardened steeland secured in dove-tail slots or side grooves in the adjacent faces ofthe two bars or shear blades by cap screws 10. The end edges of theseblades are centrally notched, as shown at 11, and are preferably madereversible by notching both ends, thus giving a longer life. Thestationary knife bar can also be reversed, as may also both the movableand the stationary bar.

The knives are of course spaced apart distances corresponding to thedistances between the wires to be cut. In the case shown, the machine isadapted for cutting American field fencing, in which the lower strandwires are closer together than the upper wires.

In the device as shown, the movable shear blade is actuated by handthrough the lever 12 pivoted between the stationary shear blade and thevertical brace 13, and having a loose slotted connection with thevertical movable shear blade.

The device is preferably located between the feeding drum and thewinding drum of a fence machine. Thus, in Figs. 4 and 5, 14 representsthe feeding drum; which in this form is shown as provided with crimpingbars 15 actuated by rollers 16 bearing upon cams 17. My shearing deviceis placed between this feeding drum 14 and the winding drum or take-upspindle 18, on which the finished fence is wound. 4 indicates the baseplate or guide for the shear, and I have shown the shear as arranged incutting position. The shear is, however, normally moved back on theguide; and after the required length of fencing has been produced andwound on the take-up spindle, the knife blades are pushed in along theguides 5 so that the wires are entered in the knife slots. The handlever is then actuated, thus shearing all of the longitudinal wiressimi1ltaneously.

The advantages of my invention result from the simplicity of the device,and the doing away with hand cutting of each successive wire of thefence. The output of a fence machine is increased; and less hand laboris necessary.

The spacing of the notches may be varied to accord with the spacing ofthe fence wires, the arrangement of the shear blades may be varied, theblade or blades may be actuated by connection with the fence machineproper, or with a power connection instead of by hand, and many otherchanges may be made without departing from my invention.

I claim:

1. A shear device for wire fabrics, having a series of shear bladesspaced apart in accordance with the fabric wires, means for adjustingthe shear device toward and from the fabric to be severed, andconnections for actuat ing the shear blades simultaneously;substantially as described.

2. In a shear device for wire fabrics, a series of notched knivesarranged to receive the wires, means for adjusting the shear devicetoward and from the fabric to be severed, and connections arranged toactuate said knives simultaneously; substantially as described.

3. In a shear device for wire fabrics, a stationary shear blade, amovable shear blade, a series of notched knives mounted in each blade,connections arranged to move one of said blades endwise and means foradjusting the entire shear device toward and from the wire fabric to besevered; substantially as described.

4. The combination with a wire fence machine, of a multiple shear devicearranged between the machine and the winding drum and adjustable to andfrom the strand wires substantially as described.

5. A shear device for wire fabrics having a series of removable andreversible shear blades spaced apart in accord' ance with the fabricwires, means for adjusting the shear device toward and from the fabricto be severed, and con nections for actuating the shear bladessimultaneously; substantially as described.

G. A shear device for wire fabrics having a series of re movable andreversible notched shear blades spaced apart in accordance with thefabric wires, means for adjusting the shear device toward and from thefabric to be severed, and connections for actuating the shear bladessimultaneously substantially as described.

7. Au attachment for wire fence machines, comprising a shear devicesupported between the take-up spindle and the crimping drum andadjustable to and from the strand wires, said shear device beingarranged to cut the strand \vires simultaneously; substantially asdescribed.

8. The combination with a wire fabric-making machine having a takeupdevice, of a multiple shear device between the machine proper and thetake-up mechanism, said multiple shear device being adjustable towardand from the plane of the fabric; substantially as described.

In testimony whereof, I have hereunto set my hand.
